BRUSH-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 384,086,dated January12, 1886.

Application filed December 26, 1884. Serial No. 151,186.

To all whom it may concern:

Be it known that I, JOSEPH M. PIOKER- ING, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a certain new anduseful Improvement in Brush-Making Machines; and I do hereby declarethat the following specification, taken in connection with the drawingsfurnished and forming a part thereof, is a clear, true, and completedescription of my invention.

My said improvement relates to that class of machines by which tufts ofbristles or other filaments are separated from a mass and convenientlypresented for removal by hand preparatory to their insertion intobrush-blocks; and said improvement is particularly applicable tomachines which embody a reciprocating semi-rotating notched disk and ahopper above said disk for the reception of the bristles, as shown anddescribed in my United States Letters Patent No. 178,556, dated June 13,A. D. 1876. Y

In my machines as heretofore constructed the notched disk in each casesupports the entire mass of bristles within the hopper, as well as theweight by which the bristles are forced downward toward the disk, andwhile said prior machines possess great practical value there is atendency with them to cut or injure the bristles and other filamentousmatters which are used in the manufacture of brushes.

The object of my present improvement is to prevent said cuttingtendency, and to that end I have provided thelower end of my hopper witha pair of bristle-supporting plates, one on each side of the disk, andhave so bent or curved said plates that they partially support thebristles and cause them to be more favorably acted upon by the notcheddisk than when the latter is alone relied upon for supporting thebristles.

To more particularly describe'my invention, I will refer to theaccompanying drawings, in which Figure 1 is a perspective view of one ofmy machines. Fig. 2 is an enlarged horizontal section of a portion ofthe same on line as.

It is to be understood that the disk A is providcd with an adjustabletangential tuft-notch, a, a cutoff, 1), (shown in dotted lines,) and a(No model.)

treadle, c, and its rod 0, substantially as shown said mass, the cut-offb closing'said notch prior to and during said forward movement, all asdescribed in my said prior Letters Patent. Beneath the treadle is theusual adjustable stop-screw, c", by which the rocking movement of thetreadle is limited. The hopper B has vertical grooves e for thereception of the weighted blade or fiat plunger f, and at the lowerfront side of the hopper there is a spring, 9, which extends a littlebeneath the mass of bristles and bears at its free end upon the edge ofthe disk A, as in my prior machines.

The supporting-plates O constitute the novel feature, and it will beseen that they are secured to the inner rear surface of the hopper, asseen in Fig. 1, andthat at their lower ends, as at h, they are bent orcurved forwardly, and afford between them a slot partially occupied bythe upper edge of the disk, as shown in Figs. 1 and 2. The mass ofbristles d are compressed between the front and rear surfaces of thehopper, and also between the lower edge of the plunger f and portions ofthe supporting-plates and a portion of the edge of the disk. The extentof the rocking or reciprocating movement of the disk is indicated by theradial dotted lines y and z, the former indicating the extreme limit ofthe rearward movement, as also shown by the position of the notch inFig. 1, and the latter the limit of the forward movement. The tuft-notchnever passes below or beyond the plane occupied by thesupporting-plates, and the bristles gathered therein during the backwardmovement of the disk are well consolidated without liability of beingcut or even unduly bent. After the cut-off has closed the tuft-notch thedisk begins its forward movement, and it will be seen that as the massof bristles gradually descends in the hopper the lower portion of themass is compacted from the rear toward the front, because of thecurvature of the plates, so as to present the erly filling the notchduring the next backside of the disk, substantially as described, 10Ward movement of the disk. whereby the cutting tendency of the disk isHaving thus described myinvention, I claim obviated, as set forth. 5 asnew and desire to secure by Letters Patent- JOSEPH M.
